“You know, my favorite country artist is from South Carolina,” the 21-year-old superstar told her audience, which then erupted in a sea of blood-curdling screams. Swift added, subtly hinting who would show up next and what song they’d perform, “And I hope it’s alright with you if we have a guest tonight.”

Within seconds, Mr. Rucker appeared at the top of Swift’s elaborate set staircase and started right into his big hit ‘Alright.’ The country singer sported his usual t-shirt, baseball cap and boots, but his home state crowd didn’t seem to mind the casual look — they sang along with every word.

Rucker descended the staircase and Swift joined him at the bottom, where they then took center stage side-by-side and finished out the song together, much to the South Carolina fans’ delight.
